“Courtesy“ in such a citation means that permission to republish has been requested and received.
Might just want to cite the original source instead
@DaveB. That’s presuming Ineos haven’t granted a release.
For the journos I think you’ll find they will have limited permissions over the digital assets for the purpose of their review.
Other publishers can then utilise elements of IP in the public domain under fair use provisions, but that explicitly prohibits reproduction.
Potential consequence is demonetisation and/or cease & desist from Ineos.
Not a lawyer, but done some internet publishing in the past.
Hope that helps!
